     Edited 7/18/17
     Sooo this is now a chaptered work. I don't know how long it will be,
     but I plan on showing small glimpses of Kim and Olivia as they grow
     up. Please feel free to drop any requests below, or you can come talk
     to me on Tumblr !
     This fic includes sexual acts between a young teen and her newborn
     niece. Since they are both minors and the baby cannot consent I've
     tagged it as non-con/rape. If you think I've left out an important
     tag please let me know.
     I never explicitly state Kim's age, but I imagine her to be around
     13ish.
     This is FICTION!
     Enjoy!

“Shit!” Glenne curses, quickly scooting away from the table and the spilled
cranberry juice. “God this is gonna stain. Kimmy, would you mind taking her and
changing her onesie? They're in the second drawer in the nursery.” Kim’s sister
in law hands over the small child, barely 1 month old.
“Sure.” Kim replies, cradling the infant to her chest and standing. She watches
Glenne rush into the house before slowly making her way inside and upstairs to
the nursery, shutting the door silently behind herself. She crosses the room
and lays her niece on the changing table. “Hi my pretty girl! I'm just gonna
get you out of these dirty clothes ok?” The child stares up at her with a
serene look on her face.
Kim carefully pulls down the stained garment, before checking to see if the
diaper was still clean. She pulls it open on each side, happy that the juice
seemed to only soil the baby's onesie.
Before re-fastening the diaper Kim runs a finger over the baby-soft skin on her
niece’s tummy, a barely there caress to the newborn’s flesh. She's distracted
by how smooth it is, running her fingers down toward her legs. The small
dimples in the skin make her smile, and she leans down to place a kiss on each
knee.
Her eyes stray to the child's small slit, barely even noticeable between her
chubby thighs. Sparing a quick glance to check that the door is secure, Kim
traces a finger along the smooth skin. She's still way too young to penetrate,
even Kim's slender fingers would cause irreparable damage to that sweet skin.
Kim longs for the day she'll be able to sink her fingers into the child's hot
cunt, finger fuck her until her wrist is coated in her nectar. But for now,
soft touches will have to do.
She leans down to place a kiss to that sweet spot, marking it as her own.
Unable to stop herself, she slips her tongue out to trace the delicate skin.
She laps gently at the minuscule cunt under her tongue, tracing the tempting
crease set between those soft lips. She carefully presses the tip of her tongue
to that slit, a soft moan escaping as she feels the welcoming heat there. It
takes all of her strength to pull back, to stop herself from devouring the
beautiful girl before her.
Straightening up, Kim quickly re-fastens the infant’s diaper and grabs a clean
onesie. Glenne is probably wondering what's taking her so long by now, and the
last thing she needs is to get caught. However, she can't withhold a small
smile as she carries the baby back down to her mother; babysitting just might
be a bit more fun than she'd expected.

***** Chapter 2 *****
Chapter Summary
     Kim's first time babysitting Olivia.
Chapter Notes
     Dedicated to IcdKoffie for being so sweet and encouraging!
Kim doesn't get recruited to babysit until nearly 6 months later. Glenne and
Troy hover around the house for 45 minutes before Kim can convince them to
finally leave for dinner. They're gonna be gone for less than two hours, and
she'll be  fine I promise just GO!
She stands at the door, Olivia on her hip, and waves as they back out the
driveway. Only when they turn the corner and are out of sight does she step
back inside and shut the door behind her. She locks the door, making sure to
flip the deadbolt too.  Finally.
 
 
After a quick diaper change, the two head into the living room. Kim sinks to
her knees in front of the couch, laying the infant on the cushion in front of
her. She simply stares at Olivia for a long time, eyes tracing every inch of
her soft little body. She's so small, so helpless. Kim just wants to  take.
She wants to be the first person to give her tiny niece pleasure. Wants to be
the first one to bring her to orgasm, wants to feel her body quake and taste
her sweet release. She wants to be the first person to penetrate that tiny
body, fuck into her mouth and pussy and ass. She wants to  claim  every fucking
bit of her.  And she will.  A shiver wracks her body as she imagines all the
things she wants to do, all the things she  will  do to the child in front of
her.
Kim slowly removes the child's onesie and diaper, trailing her fingers over the
soft flesh as it's revealed. She follows her fingers with her mouth, pressing
kisses to every place she can reach. Olivia wriggles on her back, cooing and
giggling at her aunt’s soft touches.
Her happy noises draw a smile from Kim, and she presses her lips against
Olivia's. She traces her tongue over the thin lips, darting inside to taste.
Her tongue is much too big for the infant’s mouth, but still she plunges on,
running it over pink gums and soft cheeks. She spends long moments rubbing her
tongue against Olivia's, trying to coax it into a matching rhythm, but the
child is still too young and unfocused.
When she finally detaches from her small mouth, Kim focuses on where her hands
are running up and down her sides. She rubs her thumbs over Olivia's dime sized
nipples, slightly puffy and so pale they just barely stand out against her
skin. Releasing a small groan, Kim leans in and licks a broad stripe over each
nipple in turn. Olivia continues to wriggle on the couch, soft noises of
contentment filling the air.
Kim stands and quickly sheds her clothes, before sitting next to Olivia on the
couch and drawing the baby to her nude body. She cradles her close, pressing
their bodies together to make as much skin contact as possible. She lowers
Olivia to sit on her lap, chubby little thighs on either side of Kim's thigh,
her baby cunt pressed tight against her leg. Kim shudders and rolls her hips,
falling into a slow grinding rhythm, watching her niece essentially riding her
thigh. Someday the child will be able to hold herself up and actively grind
down against her, seeking her own pleasure and racing toward orgasm.
The gentle movements have rocked the child to sleep, and Kim slows and comes to
a stop. She steadies Olivia with a hand spread across her back, then takes one
of her hands, curled into a loose fist in sleep. She presses a kiss to her
fingers before licking across each digit. A soft moan escapes as she sinks four
of the baby's digits into her mouth, suckling lightly, her hot tongue
separating and lathing each finger in turn. Once the child's hand is slick and
nearly dripping, she draws back and brings her heels up to the edge of the
couch, spreading her legs wide. She lays Olivia face down across her stomach,
one arm dangling between Kim's splayed thighs.
She takes Olivia's hand and moves it to her pussy, flattening the fingers until
she can use it to rub herself. Kim cants her hips up to get a better angle,
bringing the child’s fingers together and using them to rub circles around her
clit. She squeezes her eyes shut and drops her head against the back of the
couch. She speeds up the movement of Olivia’s hand, humping her hips up into
the movement. Biting her lip, she does her best to tamp down the noises
threatening to spill out of her mouth. Feeling her climax flying towards her,
Kim uses her own fingers to guide the child's tiny digits into her pussy.
They’re too short to give much sensation, but just knowing that it's Olivia's
fingers penetrating her is enough to bring Kim to the edge rapidly. She
whimpers and presses the baby's hand deeper, taking her entire fist inside.
She carefully guides the small fist, fucking into herself in a sloppy rhythm.
After mere seconds she screams through her orgasm, her cunt clenching down on
Olivia's hand and drenching her with her release. She shudders under the small
child, bringing her arm to a stop, still twitching through what has to be her
most intense orgasm ever.
Kim carefully withdraws the hand from inside her, making sure not to twist the
small arm and hurt the infant. She brings Olivia up to her chest, cradling her
close. The child stirs, whining softly. When she latches onto Kim's nipple she
moans softly, cupping the child's head and holding her in place. Kim brings her
free hand down to her pussy, thrusting two fingers inside before withdrawing
and using her own slick to rub roughly at her clit. Her hips rock as she gets
closer to the edge, the rhythmic suckling at her breast almost unbearably
arousing. Olivia gums at her nipple, upset when no milk is produced, and the
tiny bite sends Kim into orgasm, her entire body quaking with her release.
She flops back onto the couch, baby held tight to her chest. When her heart
rate returns to normal she carefully unlatches Olivia's mouth from her breast,
cradling her close and running a soothing hand along her side. The two lay
there for long moments, before Olivia begins to fuss and cry with hunger. Kim
presses a kiss to the downy head tucked below her own and sits up. She
carefully dresses her niece before throwing her own back on haphazardly.
Settling the infant on her hip, the two head into the kitchen.

 
When Glenne and Troy open the door later that evening, they find Kim and Olivia
curled up on the couch sleeping. They smile softly at each other and quietly
head upstairs to get ready for bed. They shouldn’t have worried, Olivia
obviously adores her aunt, and Kimmy seems to have the magic touch with their
baby girl. It’s so reassuring to know that they have a responsible babysitter
nearby.
 
***** Chapter 3 *****
Chapter Summary
     Olivia loves Nutella.
Chapter Notes
     I'm no expert, but I'm pretty sure you shouldn't give a child this
     much Nutella. That's hardly the worst thing happening here though...
     so hopefully you'll indulge me!
See the end of the chapter for more notes
The next time Kim can convince her aunt and uncle to let her babysit is just
before Olivia turns ten months old. She asks repeatedly when she can babysit
again, pestering them until they finally give in. They assume it's because she
wants the $30 they give her each time she helps out, and while that's a bonus,
it's not the reason she loves babysitting so much. It's a lot safer than the
truth though, so she doesn't say anything to dissuade them.
“Troy gave her a bit of Nutella last month and now she just goes crazy for it.
We don't like to give her too much, because it's definitely not healthy for
babies, but we figure a little bite here and there won't do any harm.” She runs
a hand over Olivia's fluffy hair. “Besides, she gets the cutest little pout
when she's begging you for it, honestly it's impossible to say no to!”
Glenne walks into the kitchen and reaches into the cupboard, pulling out a
half-full jar of Nutella. “She hasn't had any in a couple days, so I'm sure
she'll just go wild as soon as she sees it.” She opens the dishwasher and
retrieves a small plastic spoon, then sets it on top of the jar.
After Glenne and Troy say their goodbyes and smother Olivia in smacking kisses
they finally leave. Kim gets Olivia's dinner ready, then puts Olivia's yellow
ducky bib around her neck and sits her in her high chair. After the infant
eaten most of her dinner and smeared the rest all over her high chair, Kim
wipes her face with a wet towel and then sets her on the ground. As she crawls
around Kim cleans up, then eats a quick dinner herself.
She spots the Nutella as she's following Olivia into the living room, and she
stops. She grabs Olivia and plops her on the counter. Kim unscrews the lid and
scoops a bit of the thick spread onto the small spoon, popping it into her
mouth. She sucks the utensil clean before repeating the motion, this time
offering it to Olivia.
The small child goes wild, wiggling around and flailing her hands towards Kim,
making grabby hands at the spoon. Kim laughs and brings the spoon to her mouth.
Olivia wastes no time, and in a matter of seconds has sucked the spoon clean.
A wicked thought pops into Kimmy’s head, and she grins. She grabs the Nutella
and a dish towel, before scooping Olivia up and taking everything into the
living room. She sets the child on the soft carpet, and the open jar on the
coffee table. She quickly sheds her clothes, then spreads out the dish towel
and sits on top of it.
She spreads her legs wide, leaning back on one hand while the other reaches for
the Nutella jar. She withdraws the baby spoon, scooping up a dollop of the dark
spread before moving it between her spread thighs and liberally coating her
cunt. She drops the spoon onto the coffee table and calls out for Olivia.
“Livvy! Come here sweetheart, auntie Kimmy has a yummy treat for you!” She
slides a finger through the Nutella and waves it at her niece. “C’mon baby,
come eat.”
The infant catches sight of her aunt's finger and lets out a small shriek of
delight. She crawls over and grabs Kim's hand, quickly bringing it to her mouth
and sucking off the sweet spread. As soon as it's gone she whines, desperate
for more. Kimmy huffs out a laugh and draws the child between her legs. She
positions her small body directly in front of her pussy, and points.
“There's a lot more for you Liv. Look! Right there!” Olivia looks at her for a
moment, puzzled. When Kim snaps her fingers the child jolts in shock and looks
down, finally spotting her prize. She claps her hands in delight before falling
forward on all fours and crawling closer.
She leans in, tongue first, and laps at the Nutella. Kim whimpers at the first
touch of Olivia's tongue, her entire body tensing. It's unlike anything she's
ever felt, pleasure racing up her spine and moans falling unbidden from her
lips. Olivia licks with absolutely no finesse whatsoever, but Kim is in ecstasy
with each swipe of that untrained tongue.
In a matter of minutes most of the Nutella is gone. The child chases the taste,
dipping her tongue between Kim's slightly spread pussy lips. The teen quickly
reaches a hand down and spreads herself wide, and Olivia cheers at the hidden
bit of Nutella she finds there. She licks over Kim's clit, and when she goes to
move away Kim places a hand behind her head and holds her still.
“You've gotta lick more Livvy. There's still more. Right there. Oh fuck yes,
right there. Oh god!” She shivers at the small tongue repeatedly lashing at her
clit. Olivia goes to move away again, distracted in her search for more. Kim
grabs the jar and swipes her finger inside, then wipes the sticky spread
directly over her clit. “Suck it. Please Livvy, suck it- OHHH SHIT!” She child
purses her small lips around her aunt’s clit, and sucks softly. “More baby
girl. Oh shit. Oh god!” Kim cries out and presses Olivia's face closer, nearly
smothering her into her spasming cunt. An orgasm unlike any she's had before
crashes over Kim, her toes curling and her back arching almost painfully.
The child continues suckling her clit like it's her mother's tit, her lips
wrapped around the tight bud and pulling on it rhythmically, immediately
sending Kim into a second orgasm right on the heels of the first. When her body
finally stops trembling she taps Olivia's head, gently coaxing her away from
her new favorite treat.
“That's enough sweetheart. No more.” Olivia whines at the loss and pouts. Kim
manages a hoarse chuckle. “I know, I'm sorry. You can have more later, auntie
Kimmy just needs a little break. Here.” She scoops a little Nutella with the
spoon and hands it to Olivia. “Go crazy.”
Olivia coos and holds the spoon close, quickly sucking the thing clean. Damn,
that girl has one hell of a mouth. I wonder what else it can do? As she sprawls
on the carpet and catches her breath, Kimmy can't hold back a wide grin. She's
a fucking genius.
Chapter End Notes
     Damn I'm craving Nutella now.
***** Chapter 4 *****
Chapter Summary
     Olivia is really fussy. Kim is the only one who can calm her down.
Chapter Notes
     Happy new year everyone!!
Olivia has been cranky all night, and when Troy hands her over to Kim he looks
exhausted.
“I don’t know how to thank you, Kimmy. She’s been fussy all day, and I hate to
leave her but a client has an emergency and I need to go talk them down.” He
runs a hand through his hair. “She’s eaten already, I’ve been trying to get her
to sleep for almost an hour now but she just won’t settle down.”
Kim coos at the weeping child. “We’ll be alright, won’t we Livvy?” She smooths
a hand down her back, turning to her older brother. “Go. I’ll lay her down in
the guest room and see if I can get her to rest.”
Troy looks so relieved that it almost seems like he’s going to cry. “God, if
you can get her to calm down you can take everything in my wallet.” Kim laughs
softly and nuzzles at Olivia’s soft hair.
Troy quickly gets changed into some slacks and a button down, before pressing a
kiss to both of the girls’ foreheads.
“I shouldn’t be gone for more than a couple hours, but if something changes
I’ll let you know. Thanks again Kimmy!” Kim makes sure to lock up after he
leaves, then walks upstairs with the crying baby still held closely to her
chest.
“Shhh sweet girl, everything’s gonna be ok. Kimmy’s here now. Shh baby.” She
sets the infant down on the bed in the spare room. “C’mon Liv, lets get you
more comfortable.”
Kim strips them both down quickly, then carefully holds Olivia’s naked body
against her own. The baby is still fussy, so she just paces the floor for a
while, bouncing the child lightly to settle her down. She revels in the chance
to press her naked skin against Olivia's. She rarely has the chance to touch
and linger the way she craves, and this time she's making the most of their
time alone together. As she cradles the child as close as possible she runs her
free hand over petal soft skin, tracing invisible lines of worship into every
inch.
The child’s skin is hot from her obvious agitation, and Kim walks to the
attached bathroom to grab a washcloth. She runs it under some cool water,
squeezing out the excess before placing it on the back of Olivia’s neck.
“There you go sweetheart. That’s better, right? Shhh. Just calm down for Aunt
Kimmy, and I’ll make it all better I promise.”
It takes nearly 20 minutes, but the wailing child finally falls silent. When
she has finally quieted down, Kim lays Olivia down on the bed, propping her up
slightly on a pillow. She climbs onto the bed, arranging herself on all fours
in front of the small child. She just looks for long moments, taking in all of
the changes in her niece since the last time they were together. Olivia's
beautiful downy soft hair has grown, and is pulled up into a sassy little
ponytail at the top of her head.
Olivia is the most beautiful child Kim has ever seen. She takes after her
mother, with her pale skin and bright blue eyes.
She reaches forward and gently spreads Olivia's legs, positioning them so her
hot center is spread wide for her gaze. She licks her lips at the slight
parting of Olivia's vulva, the soft pink of the skin nearly begging her to
taste. She carefully draws a finger over the outer lips, tracing down one side
then the other.
Olivia giggles at her aunt's teasing touch, and Kim smiles adoringly up at her
precious niece. She's stunning, and when she grows up men and women alike will
throw themselves at her feet. But for now she's all Kim’s, and she's going to
make the most of every second she has the child all to herself.
Kim brings both hands to the child's pussy and spreads her wide with both
thumbs. She leans in close and swipes her tongue up her slit, groaning softly
at the taste. She repeats the motion, licking from perineum to the crest of her
coccyx.
Olivia squirms at every swipe of her tongue, small legs flail about, knocking
into Kim’s shoulders, but doing nothing to distract her aunt from her prize.
Still holding the outer lips wide, Kim presses her tongue into Olivia's vagina,
just barely breaching the small opening. She licks around the edges before
dipping back inside, repeating the motions over and over until the teen is able
to fuck her tongue in almost an inch deep with ease.
She loses herself for a moment between her thighs, licking into the baby's core
and swallowing her juices. Fuck Kim would live on her taste if she could.
Swallow her down for every meal, lapping at that sweet pussy day and night.
Finally she pulls back, nose and chin covered in saliva and Olivia's scent. She
licks her lips to chase the taste.
Kim presses her thumb over Olivia’s opening, adding slight pressure to feel the
edges part ever so slightly She brings her hand to her lips and sucks in her
pinkie, coating it in saliva before bringing it back between the child’s legs.
She adds more pressure now, and gasps when it presses inside.
The heat is incredible, and Kim reminds herself to take it slow. She can’t hurt
the child, would never forgive herself if she caused her any pain.
She slides her finger deeper, feeling along the silky smooth walls of her
pussy. She's actually inside Olivia. Holy shit. She adds more pressure, sliding
deeper into the child's cunt, until the digit is in up to the base.
Kim brings her other hand down to her own drenched cunt, plunging two fingers
inside and rubbing the heel of her palm against her throbbing clit.
She pulls her pinkie out of Olivia, sucking it clean before replacing it with
her index finger. It's a tight fit, the infant's body unused to such a big
intrusion, but Kim continues to massage her from the inside, and slowly the
walls relax enough for her to move her finger in and out smoothly.
As she fucks the child with her finger, she leans forward and sucks at her tiny
clit, just barely peeking out from beneath its hood. She circles the bud with
her tongue before gently suckling on it, occasionally lashing across it with
her tongue.
Olivia is writhing against the pillows, cooing softly and clenching her little
fists in the air. Kim takes the fingers from her own cunt and brings them up to
Olivia’s mouth. She traces the infant’s lips before pressing them inside,
prompting Olivia to suck.
Kim raises her head and watches, her pussy flooding at the thought of her baby
niece tasting her juices. She takes her mouth off the child’s cunt. “Aunt Kimmy
tastes good, huh baby girl? So do you.” She leans back in and presses her nose
to Olivia’s pussy, taking in a deep whiff. “The best thing I’ve ever tasted,
ever smelled.” She kisses the saliva-soaked skin. “Can’t wait until you’re
older. I’m gonna teach you everything.”
Olivia babbles happily around Kim’s fingers, her eyes growing heavy. Kim slides
them out of her mouth, and brings them down to her cunt again. She fucks three
inside herself this time, grinding down hard against her palm.
“You’re still too small for more than one finger, but when you’re old enough
you’re gonna take everything I have to give you. But for now, this is enough.”
Kim removes her index finger before burying her tongue inside the slightly
loosened cunt, pressing deep and reveling in the sweet taste.
Kim rides her fingers to the same rhythm she’s fucking her tiny niece’s hole,
and when she finally cums she whimpers into the soft flesh, unable and
unwilling to move.
She collapses against the bed when she finally comes down, her face still
resting in Olivia’s crotch. Kim stays there until she catches her breath. Once
she’s calmed, she presses one last kiss to the child’s skin, one last trace of
her tongue along the damp flesh, before she raises her head.
Olivia is sleep, her face peaceful. Kim smiles. The combination of her earlier
tantrum and Kim’s ministrations must have been too much for the small child.
Kim sits up, admiring the view for a moment, before she pulls an extra blanket
up over both of their nude bodies. She curls an arm around Olivia, before
resting her head on the same pillow, and quickly joins her in sleep.
